The invention relates to radiators for steam, hot water, or otherheating systems employing humidifying devices. It has for one of itsmain objects to provide a humidifying device, formed integrally with theradiator sections, over which a relatively shallow stream of water willow to be evaporated so as to impart water vapor to the surrounding air.

Another object is to provide means whereby the water or condensate inthe radiator sections may be trapped and conveyed to the humidifyingdevices. A further object is to so construct the devices that they maybe incorporated in radiators oi various designs andtypes,regardless ofthe manner in which they are assembled. A still further object is toprovide means for regulating the iiow of the water through thehumidifying devices. Additional objects are to provide humidifyingdevices and condensate traps and chambers in connection with radiatorsections without altering their general contour or appearances, andwithout adding greatly to their cost. These and various other objectsand advantages will be readily understood from the following descriptionand from the accompanying drawings of certain preferred embodiments ofthe invention in which, however, modifications may be made withoutdeparting from the scope of the appended claims. In the drawings Fig. 1is a side elevation of the upper part of a radiator section, shownpartly in cross section to disclose the humidifying device containedtherein;

Fig. 2 is a top View of same, also partly in cross section;

Fig. 3 is an end view of several radiator seotions connected together,one or" which is shown partly in cross section;

Figs. 4, 5 and 6 are top views showing medincations of the huinidifyingdevice;

Fig. 7 is a cross sectional side elevation taken on line '7-7 in Fig. e;

Fig. 8 is a fragmental, side elevation of the upper part of a radiatorsection, shown in cross section to disclose the condensate trapcontained therein;

Fig. 9 is a fragniental, side elevation of the upper part of a radiatorsection shown in cross section to disclose the condensate chambercontained therein;

Fig. 10 is a cross sectional side elevation of a plurality of sectionsshowing one method for trapping the condensate and delivering it to thehumidifying devices; and

Fig. 11 is a fragmental, cross sectional View illlstrating a slightlydiiierent means for doing Referring iirst to Figs. 1, 2 and 3, whichillustrate the ordinary type of radiator sections l() which areconnected side by side as shown in Fig. 3, the humidifying device orwaterV well 11 is shown located within the section and near its top.This is the preferred position, but the well may be located elsewhere inthe section and still produce the desired result. The well is castintegrally with the section so as to be completely separated from thesteam space 12. The bottom 13 of the well is substantially level butprovided with a central, upwardly-extending bailie 14. An inlet 15 andan outlet 16 are provided in the sides of the well, and orices 17 areprovided in the roof of the well; through these the water vapor escapes.

The water wells are connectedtogether byshort nipples 18, as shown inFig. 3. To assure a shallow flow of water through the wells, a device ofthe type shown at 19 is employed. It consists of a receptacle 20 intowhich water iows from a supply pipe 21. An overiiow pipe 22 is alsoconnected with the receptacle. The upper end of the overflow pipeextends above the bottom of the receptacle, as shown at 23, to insure ashallow flow of water through the outlet 24 which leads to the waterwell 11 in the iirst section; any surplus water being drained throughthe overflow pipe.

The proper depth of water is such that it will not overflow the baiilesle while flowing through the wells. Asuitable valve is connected to thepipe 21 to regulate the flow of water and a waste pipe 25 drains offwhatever water may remain unvaporized after passing through the waterwells. In practice, the now of water is so regulated that practicallyall of it will be vaporized while passing through the water wells.

Figs. 4, 5, 6 and 7 illustrate the type of radiator section which isconnected end to end instead of side by side. In this case the entiretop of each section is employed as a humidifying device. The water to bevaporized enters through inlet 26, iiows between baies 27 and isdischarged through outlet 28. The water vapor escapes through orices 29.In Fig. 6 a modification is shown wherein the water flows in oppositedirections as indicated bythearrowsBG and 31. In this case the partition32 extends to the top of the humidifying d evice and each section may besaid to contain two such devices.

instead of using water direct from the ordinary water supply, the waterfor the humidifying devices may be taken from the radiator in the caseof hot Water systems; and, in the case of systems using steam or vapor,a part of the condensate may be trapped and conveyed to the humidifyingdevices. In either case evaporation is facilitated by the highertemperature of the water, and, as the water is free from impurities nosediment is deposited in the water wells.

In Fig. 8 a section A is shown in which a trough 33 is cast below theinlet 34. This trough extends across the steam spacel2fandc0nveys to theadjoining section whatever condensate from the steam may be caughttherein. In Fig. 9 a section B is shown in which partitions 35 are castacross the steam space so as tol form a chamber 36 into which thecondensate will flow from the trough in the adjoining section. An outlet37is provided in this chamber.

Fig. 11 shows two sections A connected with a section B. The steam fiowsin the direction of the arrow 38 and the condensate, which is caught bythe trough 33, is conveyed to the chamber 36 in which it raises abovethe outlet 3'?. The pressure in the radiator forces the condensatethrough the outlet 37, up through the pipe 39, and into the water Well11, in the adjoining section A, from whence it flows through the waterwells in the other sections as indicated by the arrow 40.

Three sections A and a section C are shown in Fig. 10. The section C, inaddition to having the chamber 36, is also provided with a water welland the pipe Lil leads from the chamber to the water Well. As in Fig.1l, the steam flows in the direction of the arrow 42 and the water iiowsthrough the wells in the direction of the arrow 43. The views Figs. l0and l1 are merely shown to facilitate the description and it is evidentthat sections A, B or C may be arranged in any combination in a radiatorand that any number of each may be used in such a combination. Inpractice, a well may be placed on the pipes 39 and el.

From the foregoing it will be noted that the construction and operationof this device is very simple and that it does not alter the generaloutline of the radiator, nor does it unduly addto its cost. It will alsobe noted that by having a relatively shallow streain of Water iiowingthrough the humidifying devices, rapid evaporation will take place; themaximum evaporation being reached when the hot water or condensate isused.

While I have shown orifices, cast in the sections, through Which thewater vapor escapes, it is evident that removable, perforated coversmight be used. It is also evident that sections, such as shown at A, maybe made with or without Water wells.

While I have illustrated sections of certain types, it will beunderstood that the invention may be used in sections of other types,whether cast or made oi pressed metal. It will also be noted that thechamber 36 may be made of any other size or shape than that shown, andthat the trough 33, instead of being cast integrally with the section,might be inserted through the inlet 34.

Having described my invention and its opg eration, what I claim as newand wish to protect by Letters Patent is:

1. The combination with a radiator section of a humidifying deviceconsisting of a Well cast integrally with the section but separated fromthe steam space thereof, of means forming a tortuous water passagethrough said well, of means for inducing a shallow stream of water toflow through said tortuous passage to be vaporized by the heat in thesection, and of means through which the vapors are liberated from thehumidifying device.

2. The combination with a radiator section of a humidifying deviceconsisting of a well lo cated within the section but separated from thesteam space thereof, of a condensate-collecting chamber contained Withinthe section, of means humidifying device or devices, and means for-rliberating the vapors from the humidifying device or devices.

4. In a sectional radiator, one or more sections having condensateconveyers, one or more sections having condensate-collecting chambers,1;

one or more sections having humidifying device means for conveying thecondensate from said chamber or chambers to the humidifyingdevice ordevices, and means for liberating the vapors 'from the said humidifyingdevice or devices.
